HOUSTON — The Houston Astros have fired manager Bo Porter in his second season with the club.

General manager Jeff Luhnow says the decision wasn’t based on Houston’s record but because “we need a new direction in our clubhouse.”

The Astros entered Monday in fourth place in the AL West with a 59-79 record, second worst in the league.

Bench coach Dave Trembley was also let go and Tom Lawless takes over as interim manager. Lawless worked in Houston’s minor league system and was the interim manager at Triple-A Oklahoma City this season when manager Tony DeFrancesco was on medical leave.

Porter joined the Astros for the 2013 season after working as a third base coach for the Washington Nationals.

Adam Everett, who was also working in the minors, will replace Trembley.
